Abstract: The present invention provides an electrically-insulating wire management assembly for a metallic electrical distribution device housing. The assembly includes at least one slot having a generally v-shaped length formed at an angle through the cross-section of the assembly's body. Each slot is arranged to receive a flexible electrical conductor through one open side edge of the body and guide the conductor entering through the outer face of the body, across the length of the slot, and exiting through the inner face of the body into the housing interior. The angle of each slot is adapted to provide an interference fit with the conductor. The assembly includes means for securing the assembly to the side wall of the housing in a position allowing the conductor to enter the housing through the assembly. The present invention also includes an electrical distribution device housing adapted for connecting with a wire management assembly.
